Related to the machine.
  • the box making machine that manufactures cardboard boxes is equipped with a counter ejector that stacks and counts the sheet-like cardboard boxes (hereinafter also referred to as sheets) that have been boxed at the most downstream position, and stacks and discharges them in batches.
  • This counter ejector has a hopper for stacking sheets, and the movement in the conveyance direction of the sheet fed upward from the feeding roll toward the horizontal or substantially horizontal direction is stopped by a front stop (front plate). Drop it into the stack and stack a predetermined number of sheets.
  • the front stop collides with the front end of the sheet that is fed almost horizontally onto the hopper, which may cause damage to the front end of the sheet or the front stop itself.
  • the speed of the box making machine has been increased, and the leading edge of the sheet collides with the front stop at a higher speed, so the risk of such damage becomes more significant. Therefore, a technology relating to the front stop has been developed that improves the durability of the front stop itself while buffering the collision of the front end of the seat.
  • Patent Document 1 discloses a front stop that includes a protection plate with which the front end of the sheet collides, a leaf spring that contacts the back surface of the protection plate, and a support plate that is provided on the back surface of the leaf spring via sponge rubber.
  • the protective plate is made of hard resin
  • the leaf spring is made of metal
  • the support plate is made of steel.
  • the protection plate is installed with the surface for receiving the front end of the sheet facing the vertical direction so as to face the sheet conveyed substantially horizontally.
  • the protective plate Since the protective plate is made of hard resin and is elastically supported from the back by a leaf spring, when the leading edge of the sheet collides with the protective plate, the protective plate stops while the sheet is displaced according to the elastic deformation of the leaf spring. . For this reason, the sheet can be stopped while avoiding damage to the protective plate and the sheet.
  • the support plate that supports the protection plate and the leaf spring from the back side is fixed to the protection plate and the leaf spring in a non-contact manner so that the stress concentration is alleviated and the durability of the front stop itself is improved. It is supposed to improve.
  • Patent Document 2 although it is not the front stop of the counter ejector of the box making machine, the postcard reject stacker device is inclined slightly upward with respect to the vertical direction at the portion where the tip of the loaded postcard collides.
  • An inclined plate (corresponding to a front stop) is provided, and a roller is provided above the inclined plate.
  • the front stop must be able to absorb the shock even for heavy sheets.
  • elastic deformation of an elastic body such as a leaf spring of Patent Document 1, for example.
  • the inclined plate of Patent Document 2 does not use elastic deformation and cannot sufficiently absorb the impact of a heavy sheet as compared with a postcard unlike a cardboard box.
  • the elastic body since the elastic body is always restored when the elastic deformation of the elastic body is used, the sheets may be greatly bounced in the direction opposite to the traveling direction due to the restoring force, and the sheets may not be easily aligned when stacked.
  • the sheet is sandwiched and fed by the feed roll disposed on the upstream side in the transport direction above the hopper, the sheet is fed with the rear end side being restrained by the feed roll and the front end side being sent out in a free state.
  • the front end collides with the front stop in a state where the front end side as a free end hangs down, that is, in a forward tilted state.
  • the forward tilt becomes more prominent.
  • the rear end of the sheet In the forward tilted state, the rear end of the sheet is at a high position, so the front end of the succeeding sheet collides with the rear end of the sheet stopped by the front stop, causing damage such as bending of each sheet, or There is a possibility that the sheet may not be properly laminated due to jamming up.
  • a technology is known in which a blower is installed above the vicinity of the feed roll and the rear end of the sheet is pressed downward by wind pressure, but even if this is used, the wind pressure acts on the rear end of the sheet. After the feed roll is removed, if the sheet conveyance speed is high, the subsequent sheet enters before the wind pressure acts on the trailing edge of the sheet, and the collision of the subsequent sheet cannot be sufficiently avoided. .
  • An object of the present invention is to provide a front stop device, a sheet stacking device using the same, a counter ejector, and a box making machine, which can avoid problems caused by the above.
